Which two statements accurately describe a visualization animation?

Tableau visualization animations can use either a Simultaneous or Sequential animation style, and their analytical purpose is to make changes in the data easier to perceive. Therefore, A and D are correct. Under Format > Animations, Tableau provides two animation styles. With Simultaneous, all applicable transitions occur at the same time. With Sequential, Tableau stages the transition—for example, fading marks, moving or sorting them, and then displaying the updated state. This directly confirms option A. Animations are particularly useful when filters, sorts, parameters, or other changes alter the position or composition of marks. Instead of immediately replacing one static state with another, the transition helps a viewer understand how the marks changed, making patterns, movements, and differences easier to track. This supports D. The Pages shelf is a separate Tableau feature for stepping through members of a field and can create a sequence of views, but it does not define visualization animations themselves. Likewise, animation is a workbook/sheet formatting capability rather than a feature specifically defined by map visualization usage. Tableau's official Animations documentation identifies Simultaneous and Sequential as the available animation styles and describes animations as a mechanism for visually communicating changes in the view.
